Home page with pipe character opens extra tabs when Firefox starts

Firefox sets multiple home pages when you separate each address with a pipe character (|) or vertical bar. This feature may lead to problems when an individual home page address contains a pipe character.

Here's how to fix it:

  1. Click the menu button New Fx Menu Fx57Menu and choose Options.Preferences.
  2. Select the General panel.
  3. In the Home Page text box, replace all pipes (|) with %7C.
  4. Close the about:preferences page. Any changes you've made will automatically be saved.
  1. Click the menu button New Fx Menu Fx57Menu and choose Options.Preferences.
  2. Select the Home panel.
  3. In the Homepage and new windows text box for Custom URLs…, replace all pipes (|) with %7C.
  4. Close the about:preferences page. Any changes you've made will automatically be saved.
Tip: If removing the pipe character doesn't solve the problem, add-ons or malware might be causing this behavior. Try refreshing Firefox to remove add-ons without erasing your browsing information and bookmarks.
